Koloboke Compile: NullPointerException at compile time

[Neiko2002]

Reproduce:

• clean install of Eclipse Oxygen Java JDK 1.8.0_144 on Windows 10 Build 1703
• add a new Java project to eclipse
• download the koloboke-compile-0.5.1.jar and koloboke-impl-common-jdk-1.0.0.jar into a "lib" directory inside the project
• add both libraries to the build path of the project (Java Build Path->Libraries->Add JARs)
• activate annotation process in the project settings (Java Compiler->Annotation Processing)
• add the annotation compiler to the project settings (Java Compiler->Annotation Processing->Factory Path)
• create a new file called MyMap.java and enter the example code:

import java.util.Map;

@KolobokeMap
abstract class MyMap<K, V> implements Map<K, V> {
    static <K, V> Map<K, V> withExpectedSize(int expectedSize) {
        return new KolobokeMyMap<K, V>(expectedSize);
    }
}

Afterwards Eclipse shows an error at the MyMap class name and presents the following exception:

Do you have any idea what this could be? I did not use maven or gradle to make this example simple and reproduceable. Other annotation processors work (like AutoValue) using the same steps.
